当您设置好飞利浦 Hue 系统(Philips Hue system)（飞利浦 Hue(Philips Hue)智能灯泡和相关的飞利浦 Hue(Philips Hue)桥接器）后，一切都非常好。您可以用手机甚至台式电脑控制灯泡。您正在享受飞利浦 Hue(Philips Hue)灯提供的所有氛围和自动化。
但是，有时应用程序可能会说飞利浦 Hue(Philips Hue)灯无法访问。是什么导致了这个问题，你能做些什么呢？在本文中，您将了解导致此问题的最常见原因以及如何解决该问题并将飞利浦 Hue(Philips Hue)灯泡重新连接到整个智能家居。
1. 您的移动设备(Mobile Device)是否在同一个 Wi-Fi 网络(Same Wi-Fi Network)上？
当飞利浦 Hue应用程序无法访问您的(Philips Hue)飞利浦 Hue(Philips Hue)灯时，最常见的问题是您的移动设备与飞利浦 Hue(Philips Hue)集线器不在同一个网络上。
您可以通过几种方式在移动设备上进行检查。首先要检查的是您的移动设备上是否确实启用了 Wi-Fi(Wi-Fi enabled on your mobile device)。在Android上，您可以通过在主屏幕上向下滑动并检查 Wi-Fi 图标是否已启用来快速检查。在 iPhone 上，只需检查屏幕顶部的状态栏是否有 Wi-Fi 图标。
如果它已启用，但飞利浦 Hue(Philips Hue)灯仍然无法访问，则您必须深入挖掘。在Android上，打开您的设备设置(Settings)菜单，选择连接(Connections)，然后在选择器附近的Wi-Fi下查看网络名称。在 iPhone 上，从主屏幕中选取“设置”(Settings) > “ Wi-Fi ”。您应该会在所连接的网络名称旁边看到一个蓝色勾号。
如果此网络名称与您首次设置时连接到飞利浦 Hue(Philips Hue)网桥的网络不匹配，您需要将移动设备网络更改为该网络，然后才能控制飞利浦 Hue(Philips Hue)灯。
2. 确保飞利浦 Hue 灯(Philips Hue Lights)已开启
这似乎是常识，但您可能会惊讶于忘记电灯开关关闭导致飞利浦 Hue(Philips Hue)灯变得无法被应用程序访问的频率。
确保控制正确飞利浦 Hue(Philips Hue)灯泡的开关已打开。如果您使用调光开关来控制灯光，请确保开关处于打开状态，否则灯光可能无法工作。或者，如果您需要该功能，您可以购买Hue调光开关配件。
3.仔细检查飞利浦 Hue 桥接连接(Double-Check Philips Hue Bridge Connections)
如果您知道您的移动设备与飞利浦 Hue(Philips Hue)网桥连接到同一网络，那么接下来要检查的是网桥本身。
首先，从飞利浦 Hue(Philips Hue)桥接器的背面追踪每根电缆，并确保它们连接正确。
- 电源线应连接到附近的插座，并且您应使用飞利浦(Philips)提供的原厂电源适配器。
- 以太网端口的以太网电缆应插入路由器背面的编号LAN端口之一。(LAN)确保(Make)它没有意外插入传入的互联网端口（通常标有地球图标）。
如果您已确认一切都已正确连接，接下来要检查的是飞利浦 Hue桥接器是否已通过检查(Philips Hue)飞利浦 Hue(Philips Hue)应用程序中的连接状态正确连接到网络。
启动应用程序并选择右下角的设置。(Settings)
这将打开Settings窗口，您将在其中看到Hue Bridges下列出的所有已安装的网桥。这里的状态应该是 green 和Active。选择 Hue Bridges(Select Hue Bridges)，您将在下一个窗口中看到列出的网络连接信息。这包括连接状态及其网络 IP 地址。
如果您没有看到绿色的已连接(Connected)状态或未列出 IP 地址，则您的飞利浦 Hue(Philips Hue)网桥可能存在网络连接问题。如果是这种情况，请尝试以下故障排除提示。
- 从Philips Hue桥接器上拔下电源，等待几秒钟，然后重新插入。
- 更换将网桥连接到路由器的以太网电缆，因为该电缆可能有故障。
- 将琴桥翻转过来并使用尖头工具按住复位按钮 5 秒钟来复位琴桥。此按钮位于标签恢复出厂设置(restore factory settings)旁边。
如果您确实必须重置网桥，则需要再次完成首次安装时所经历的设置过程。
4.飞利浦 Hue 灯是否添加(Philips Hue Lights Added)到正确的房间(Correct Room)？
如果您在飞利浦 Hue(Philips Hue)应用程序中设置了多个房间，或者启用房间的开关没有打开灯，则您在应用程序中为每个房间添加灯光的方式可能存在问题。
要检查这一点，请从主应用程序屏幕点击您要检查的房间。您应该会看到列出的每个Philips Hue 都已(Philips Hue)安装并希望在该房间进行控制。如果您在那里没有看到其中一个灯，则需要添加它（通常，这涉及将其从您可能不小心分配到的不同房间中移动。
为此，只需在“房间(Room)”窗口中点击屏幕右上角的三个点，然后选择“编辑房间”(Edit Room)。
最后要检查的是，即使您的所有灯都列在正确的房间中，其中一个也可能被单独禁用或关闭。如果开关在左侧并且亮图标显示为暗图标，您会看到这一点。
5. 重启你的 Wi-Fi 路由器
最常解决内部网络和互联网连接本身的(and the internet connection itself)连接问题的一件事是重新启动您的 Wi-Fi 路由器。
为此，只需按照以下步骤操作。
- 拔下路由器的电源插头。
- 等待至少 30 秒。
- 重新插入路由器的电源线。
- 等待(Wait)所有路由器指示灯恢复正常的常亮或绿色闪烁状态。
重新启动路由器后，请尝试再次连接到飞利浦 Hue(Philips Hue)灯。
6.确保你的路由器没有阻塞色相桥(Hue Bridge)
虽然这不太可能，但您的路由器中可能有一个设置发生了变化，并阻止了飞利浦 Hue(Philips Hue)桥接器与网络的连接。
默认情况下，设备通常不会被阻止，因此必须有人进行设置才能导致问题。但最好确认网桥至少连接到路由器没有任何问题。
为此，请连接到您的默认网关 IP（通常为 129.168.1.1 或 10.0.0.1，但您可以通过在命令提示符中键入ipconfig命令来检查）。(ipconfig)
以管理员身份登录(Log)您的路由器，然后在网络连接菜单下（这因路由器而异），找到设备(Devices)选项。
您应该看到所有连接的设备及其连接类型。由于飞利浦 Hue(Philips Hue)桥很可能是通过以太网连接的少数设备之一，您应该会看到它以该连接类型列出。
设备(Device)名称的最后四位数字将与飞利浦 Hue(Philips Hue)网桥背面的序列号匹配。
通过检查家长控制(Parental Controls)下的服务阻止(Service Blocking)或设备阻止(Device Blocking)来确保此设备未被阻止（同样，这可能因路由器而异）。
通常，此列表将为空白。如果您确实看到此处列出的Philips Hue桥接器，只需将其从列表中删除。
检查路由器的以太网端口是否正确检测到连接的设备也没有什么坏处。检查路由器中的以太网菜单选项，并为(Ethernet)Hue网桥连接的端口号查找除 Disconnected 以外的任何内容。
<<4-以太网端口.jpg>>
如果状态为已断开连接，请尝试将您的飞利浦 Hue(Philips Hue)网桥切换到其他路由器以太网端口，以查看是否可以解决飞利浦 Hue(Philips Hue)灯无法访问的问题。如果您必须修复这些设置中的任何一个，您的飞利浦 Hue(Philips Hue)灯可能会重新连接。
7. 测试更换的飞利浦 Hue 灯泡(Replacement Philips Hue Bulb)
无论您的所有灯泡都没有连接，或者只是一个灯泡有问题，购买一个飞利浦 Hue(Philips Hue)智能灯来测试安装它是否能解决问题都没有什么坏处。
如果您的所有灯都无法正常工作并且新灯修复了其中一个，那么您可能还需要更换所有灯泡。
希望上面的故障排除技巧可以帮助您重新连接智能灯(your smart lights)！
Philips Hue Lights Unreachable? 7 Things to Try
When you’ve set up your Philips Hue system – the Philips Hue smart bulbs and associated Philips Hue bridge – everything is excellent. You can control the light bulbs with your mobile phone and even your desktop computer. You’re enjoying all of the ambiance and automation that Philips Hue lights offer.
However, there are times when the app may say that the Philips Hue lights are unreachable. What causes this issue, and what can you do about it? In this article, you’ll learn the most common causes of this problem and how you can fix it and get your Philips Hue light bulbs connected to your overall smart home again.
1. Is Your Mobile Device On the Same Wi-Fi Network?
The most common issue when your Philips Hue lights are unreachable by the Philips Hue app is that your mobile device isn’t on the same network as the Philips Hue hub.
You can check this on your mobile device in a few ways. The first thing to check is that you actually have Wi-Fi enabled on your mobile device. On Android, you can quickly check this by swiping down on the home screen and checking that the Wi-Fi icon is enabled. On iPhone, just check the status bar at the top of the screen for the Wi-Fi icon.
If it is enabled, but Philips Hue lights are still unreachable, you’ll have to dig a little deeper. On Android, open your device Settings menu, select Connections, and look at the network name under Wi-Fi near the selector. On iPhone, choose Settings > Wi-Fi from your home screen. You should see a blue tick next to the name of the network you’re connected to.
If this network name doesn’t match the network connected to your Philips Hue bridge when you first set it up, you’ll need to change your mobile device network to that one before you can control the Philips Hue lights.
2. Make Sure the Philips Hue Lights are Powered On
This may seem like common sense, but you might be surprised how often forgetting a light switch is off leads to Philips Hue lights becoming unreachable by the app.
Ensure the switches that control the correct Philips Hue bulbs are turned on. And if you’re using a dimmer switch to control the lights, make sure the switch is on, otherwise the lights may not work. Or you can purchase the Hue dimmer switch accessory if you want that feature.
3. Double-Check Philips Hue Bridge Connections
If you know that your mobile device is connected to the same network as your Philips Hue bridge, then the bridge itself is the next thing to check.
First, trace each of the cables from the back of your Philips Hue bridge and make sure they’re correctly connected.
- The power cord should go to a nearby outlet, and you should be using the original factory power adapter supplied by Philips.
- The ethernet cable from the ethernet port should go into one of the numbered LAN ports on the back of your router. Make sure it isn’t accidentally plugged into the incoming internet port (usually labeled with a globe icon).
If you’ve confirmed everything is wired up correctly, the next thing to check is that the Philips Hue bridge is correctly connected to the network by checking the connection status in the Philips Hue app.
Launch the app and select Settings at the lower right corner.
This will open the Settings window, where you’ll see all installed bridges listed under Hue Bridges. The status here should be green and Active. Select Hue Bridges and you’ll see the network connection information listed on the next window. This includes the connection status and its network IP address.
If you don’t see a green Connected status or no IP address listed, your Philips Hue bridge could be having a network connection issue. Try the following troubleshooting tips if that’s the case.
- Unplug the power from the Philips Hue bridge, wait a few seconds, and then plug it back in.
- Swap out the ethernet cable connecting the bridge to the router since this cable could be faulty.
- Reset the bridge by turning it over and using a pointed tool to press and hold the reset button for 5 seconds. This button is next to the label restore factory settings.
If you do have to reset the bridge, you’ll need to go through the setup process again that you walked through when you first installed it.
4. Are the Philips Hue Lights Added to the Correct Room?
If you’ve set up multiple rooms in your Philips Hue app or enabling the switch for a room isn’t turning on the lights, there could be an issue with how you’ve added lights to each room in the app.
To check this, from the main app screen tap the room that you want to check. You should see every Philips Hue listed that you’ve installed and want to control in that room. If you don’t see one of those lights there, you’ll need to add it (usually, this involves moving it from a different room you may have accidentally assigned it to.
To do this, just tap the three dots at the top right corner of the screen in the Room window, and select Edit Room.
The last thing to check is that even if all of your lights are listed in the correct room, one of them could be disabled or turned off individually. You’ll see this if the switch is to the left and the light icon displays as a dark icon.
5. Reboot Your Wi-Fi Router
One thing that most commonly fixes connection issues, both on internal networks and the internet connection itself, is restarting your Wi-Fi router.
To do this, just follow the steps below.
- Unplug your router’s power plug.
- Wait at least 30 seconds.
- Plug the router’s power cable back in.
- Wait for all router lights to come back in their normal solid or green blinking state.
Once you’ve restarted your router, try connecting to the Philips Hue lights again.
6. Make Sure Your Router Isn’t Blocking the Hue Bridge
While it’s unlikely, there could be a setting in your router that changed and is blocking the Philips Hue bridge connection to the network.
Devices typically aren’t blocked by default, so someone would have had to set this up to cause a problem. But it’s a good idea to confirm that the bridge is at least connected to the router without any problems.
To do this, connect to your default gateway IP (this is usually 129.168.1.1 or 10.0.0.1, but you can check this by typing the ipconfig command into the Command Prompt).
Log into your router as an administrator, and under the network connections menu (this varies from router to router), find the Devices option.
You should see all connected devices and their connection type. Since it’s likely that the Philips Hue bridge is one of the few devices connected via ethernet, you should see it listed with that connection type.
The last four digits of the Device name will match the serial number on the back of your Philips Hue bridge.
Ensure this device isn’t blocked by checking Service Blocking or Device Blocking under Parental Controls (again, this may vary between routers).
Usually, this list will be blank. If you do see the Philips Hue bridge listed here, just remove it from the list.
It also can’t hurt to check that the router’s ethernet port properly detects a connected device. Check the Ethernet menu option in the router and look for anything other than Disconnected for the port number the Hue bridge is connected to.
<<4-ethernet-port.jpg>>
If the status is Disconnected, try switching your Philips Hue bridge to a different router ethernet port to see if that fixes this issue with your Philips Hue lights being unreachable. If you had to fix any of these settings, it’s likely your Philips Hue lights will reconnect.
7. Test a Replacement Philips Hue Bulb
Whether all of your bulbs aren’t connected, or it’s just a single bulb with a problem, it can’t hurt to purchase a single Philips Hue smart light to test if installing it fixes the problem.
If all of your lights aren’t working and a new light fixes one of them, maybe you’ll need to replace all bulbs as well.
Hopefully the troubleshooting tips above have helped you get reconnected with your smart lights!
